1) Raise the elevator mechanism.
2) Insert the forceps through the slit in the rubber inlet seal. Be certain to hold the forceps handle in such a way to ensure that the
jaws of the forceps are in a fully closed position during insertion.
3) Once the accessory reaches the elevator, the mechanism should be lowered to allow accessory advancement of about 1 cm. The
elevator may now be maneuvered as needed to bring the accessory into view and to aid in the application of the endoscopic accessory.
